I have run into a couple of cases where I wanted the kdc to provide -- not a service ticket -- but an actual encryption key for some data at rest. (Specifically an encrypted disk or a database.)

There are obvious problems to be addressed, or at least agreed to. But just generally is it worth talking about or should we leave this space to the HSM folk?
